Description

Technical Field

[0001] The utility model belongs to the field of bellows equipment, in particular to a bellows with a metal braided outer tube protection. Background Art

[0002] A bellows is a tubular elastic element with a corrugated wall. At present, bellows have some obvious disadvantages without the protection of a metal braided outer tube. First, its compressive resistance is relatively limited. Due to the structural characteristics of the bellows itself, it is easy to deform or even break when subjected to high external pressure. This is mainly because the corrugated structure of the bellows is prone to local stress concentration under pressure. The conventional solution is to increase the wall thickness of the bellows or use higher strength materials, but this will increase costs and may affect the flexibility and telescopic properties of the bellows. Secondly, the wear resistance of the bellows is poor. In the case of frequent friction or contact with other objects, the wall of the tube is easily damaged, thereby reducing its service life. This is because the surface of the bellows is relatively soft and not strong enough. A common solution is to apply a wear-resistant coating on the outside of the bellows, but this coating may wear off as the use time increases, and needs to be reapplied regularly, which increases maintenance costs and workload, so it is necessary to propose a new structure to solve the above technical problems.

[0023] When in use, the user first fixes the bellows body at the required installation position through connecting flange 100 and connecting flange 2. After the bellows body is fixed through connecting flange 100, connecting flange 2 and bolts, the ceramic rings 110 on the upper and lower surfaces of connecting flange 100 and connecting flange 2 can play a sealing role.
